Inherited permission access via enabled Electron fuses
Published Jan 28, 2024 · Updated Jun 3, 2025
Code injection in Vercel Hyper 3.4.1 and earlier for macOS allows local users to execute JavaScript with Hyper's permissions. With Electron's runAsNode and enableNodeCliInspectArguments fuses enabled, the executable honors the ELECTRON_RUN_AS_NODE environment variable and Node inspection flags instead of enforcing normal application startup. Electron disputes the remote-code-execution claim because an attacker must already execute commands locally, and reuse only inherits permissions previously granted to Hyper.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
